Development of Fluorescent Dyes

Fluorescent dyes, dyes that can emit fluorescence, refer to materials that absorb light waves of a certain wavelength and can emit more than absorbed light waves. The structure of common fluorescent dyes contains a conjugated double bond system, which can be used alone or in combination. Based on the high sensitivity and high cost performance of fluorescent dyes, it can be widely used in the fields of fluorescent labeling, fluorescent immunology, biological staining and imaging. Fluorescent reagents absorb short-wavelength light and emit long-wavelength light, so that various colors are displayed, so it can also be used as a background staining control. Here, researchers at Alfa Chemistry extend the scope of fluorescent dyes to all materials with fluorescent properties, including traditional fluorescent dyes, fluorescent labeling reagents, bioactive fluorescent reagents, fluorescent whitening agents and fluorescent color for liquid tracking reagent.

The Services

Alfa Chemistry broadly focuses on fluorescent dyes, including bioactive fluorescent dyes and reagents, fluorescent whitening agents, fluorescent dyes for biochemical analysis. Our researchers have developed a series of fluorescent dye products through advanced technology, and the development services we can provide include but are not limited to:

• Fluorescent dye and reagent development

Application of High-quality Fluorescent Mmaterials

• Immunoassay: Immunofluorescence technology is the earliest method in the development of labeling immune technology, and it is an efficient immune labeling technology. Fluorescent pigments can be combined with antibody globulins to detect or localize antigens, and can also be combined with other proteins to detect or localize antibodies. Fluorescent reagents can be used for highly efficient fluorescent probes, commonly used are fluorescein isothiocyanate (FITC), phycoerythrin (PE).
• Aqueous tracking dyes: Typically samples in water need to be analyzed, thus requiring efficient labeling with fluorescent dyes.
• Nucleic acid detection: Nucleic acid fluorescent dyes can be used for qualitative or quantitative research on cells after staining, and are suitable for the study of the interior of cells. Commonly used dyes suitable for the interior of cells include propidium iodide (PI), DAPI, thiazole orange, and acridine orange.

Our Service Commitment

Alfa Chemistry continues to develop and expand the products of fluorescent dyes. Our professional knowledge is efficient and solid. As a supplier of fluorescent dyes, we can quickly develop fluorescent dyes that meet environmental protection requirements.

Research direction

Fluorescent dyes based on small molecules can be widely used in drug discovery, cell analysis and environmental detection, etc. Compared with fluorescent dyes, near-infrared dyes have lower fluorescence background and are more widely used. Therefore, more research is focused on developing high-performance fluorescent dyes for a wide range of biological applications.

The choice of fluorescent dyes usually depends on the specific experimental solution and needs to be matched with the experimental equipment and instruments. Our researchers have many years of experience in related fields and can help customers choose suitable fluorescent dyes.
